CAR-AXLE-BOX LID.

Specification of Letters Patent.

Patented July 2, 1907.

Application filed March 26,1906. Serial No. 307,986.

To all whom it may concern:

Be it known that I, WALDEMAR ERICKSEN, a subject of the King of Denmark, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Car- Axle-Box Lids; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others'skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved car axle box lid, and to this end it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Referring to the drawings, Figure l. is a view in front elevation, showing the improved box and lid. Fig. 2 is a side elevation of the parts shown in Fig. 1, part of the box being broken away. Fig. 3 is a view corresponding to Fig. 2, but showing the lid in an open position; and Fig. 4 is a vertical section taken through the box and the lid, approximately on the line as x of Fig. 1, some parts being shown in full.

The axle box 1 is of the usual construction, except that in its open outer face it is formed with an annular flange 2 that affords a seat for the axle box lid 3. This axle boxlid 3 is, as shown and preferred, of disk-like form and in its inner face it is formed with an annular groove that receives and closely fits the annular rim 2 of the box. The box 1 is provided with a heavy hinge bolt 5, the projecting ends of which are flattened at 6, thereby affording angular trunnion-like projections on the opposite sides of said lug 4. The hinge bolt 5 is rigidly secured in the lug 4 by pin, key, screw or other suitable device (not shown).

The numeral 7 indicates a lid supporting arm, the upper portion of which is bifurcated and which is formed in the upper ends of its prongs, with seats 8 that adapt the arm to move pivotally on the angular trunnionsG. These seats 8' are formed with angular extensions 8 and 8 that extend at an angle of about ninety degrees to each other, and are adapted to be engaged with the flattened trunnions 6, as and for the purposes hereinafter described. The depending free end of the arm 7 is adapted to interlock with a lug 9 on the lower and outer portion of the box 1. The free end of said arm 7 can, with the construction illustrated, interlock with the lug 9, as shown in Figs. 2 and 4, only when the arm is dropped downward so that the seat extensions 8 engage with the flattened trunnions 6. The upper and outer portion of said lug 9 is preferably beveled, so that the said arm canv be forced into engagement therewith, by an inward and downward swinging movement.

The numeral 10 indicates a thrust bolt which has screw-threaded engagement with the intermediate por- 1 tion of the lid supporting arm 7, and at its inner end is provided with a head that is loosely swiveled in a pocket or seat 11, located at the central portion of the lid 3, The lid may, therefore, be moved laterally with furthermore, is free to adapt itself to the face of the box, regardless of the exact adjustment of the lid supporting arm and thrust screw. To hold the lid against rotation with respect to the arm 7, it is, as shown, provided with lugs 12 that work loosely between the prongs of said arm. A hand-piece or lever 13 is secured to the outer end of the thrust bolt 10, and serves as means for rotating the same. The numeral 14 indicates a stop on the lower portion of the arm 7 in which the handto close the lid against the box. The adjustment of the parts should be such that the lid will be tightly closed against the box when the hand-piece 13 is engaged with the stop 14. Considerably less than a complete rotation of said screw is required to release the lid from the box.

When the arm 7 is interlocked with the box in the position shown in Figs. 2 and 4, the lid is pressed against the box, the engagement of the ribbed seat 2 with the groove .in the box lid, holds the said lid and hence, the said arm 7, locked against upward sliding movements. Hence, it of course follows that the arm 7 is locked against movement whenever the lid is clamped against the face of the box. When, by a movement of the thrust screw 10, the lid 3 is' moved laterally away from the face of the box, the arm 7 may be slid endwise upward so as to move the seats 8 again into alinement with the flattened trunnions 6 and thereby to permit pivotal movement of the said arm. The said arm may then be moved upward in the position shown in Fig. 3, so as to carry the lid in an open position, and the said arm and lid may then be locked in that position by engaging the seat extensions 8 with the flattened trunnions 6, as shown in said Fig. 3.

With this arrangement, pivotal movement of the lid is not required in order to press its seat on the box, and this is an important feature because very considerable force is required to rotate the lid against the face of the box.

The lid is of small cost, may be very easily and quickly manipulated, and serves to form a very close joint between thebox and thelid. In fact, ajoint which is dust proof and air and oil tight may be formed between the box and the lid when desired.

I do not herein broadly claim, the combination with an axle box, of a lid supporting arm connected thereto for pivotal and sliding movements and having interlocking engagement with the box, under its sliding movements, and a lid connected to said arm, by a device permitting said lid to move laterally with respect to said arm to and froma seated position on the box,

respect to the arm 7 without itself being rotated, and,-

piece 13 engages, to limit its movement in a direction said lid having interlocking engagement with the box, when Seated thereon, and arranged to lock said arm against; sliding movement and hence interlocked to the box, inasmuch as the same is disclosed and claimed in the application of Frederich Hachmann and Waldemar Ericksen, S. N. 301,387, filed February 16, 1906, car axle box lids.

What I claim is:

1. The combination with a box, of a lid supporting arm pivoted thereto and arranged to interlock therewith, by an endwise sliding movement, a non-rotary lid, and a thrust bolt swiveled to said lid, having threaded engagement with said arm and provided with a hand-piece for rotating it, substantially as described.

2. The combination with an axle box, of a lid support ing arm connected thereto for pivotal and endwise movemcnts, and having, at its free end, interlocking engage ment with the box. under its endwise sliding movement, and a non-rotary lid connected to said arm, with freedom for lateral movements with respect thereto, into and out the box, whereby, when the lid is closed, said arm is held against endwisc movements, substantially as described.

4. The combination with an axle box, 01? a lid support ing arm connected thereto for pivotal and endwise sliding movements. and having, at its free end. interlocking engagement with the box, under its endwise movement, a thrust bolt having threaded engagement with the, interme diate portion of said arm and provided with a handpiece for turning it, and a lid swiveled to the inner end of said thrust bolt, and having interlocking engagement with the box. when closed, and which lid is movable into and out of engagement with the box by said thrust b0lt. su|)st:illtially as described.

5. The combination with an axle box, of a lid supporting arm connected thereto by an interlocking pivot joint. and having interlocking engagement. at its free end. by an endwiso sliding movement, a thrust bolt having screwthleaded engagement with the intermediate portion of said arm, and provided, at its outer end, with a handpicce, and a non-rotary lid swiveled to the inner end of said thrust bolt and having interlocking engagement: with the box, when closed, substantially as described.

In testimony whereof I atiix my signature in presence of two witnesses.
